Note:

These plots were generated with the default matplotlib parameters,
plus a default colormap that was set to gray-scale and no
interpolation. You can do the same on your system by adding the following
to your ~/.matplotlib/matplotlibrc file:

image.cmap : gray
image.interpolation : none

Without this change, most styles will default to the "jet" colormap, which is
terrible
for so
many
,
many
reasons
.

Built with Matplotlib 1.5.1.
